Answer first
All five visible World 4 Levels were completed
The current selector displayed World 4, Levels 1–5. We completed all five on July 27, 2026, and the Level 5 finish opened World 5, Level 1.
Levels 1, 2, 3 and 5 were finished without their moons. The tested Level 4 growth route collected its moon, so that Level’s moon requirement remains unknown instead of being guessed.
Current-build evidence: S15. Recorded-route cross-check: S8.
World 4 · Level 1
shifting-room return
Starting layout
Oozy starts on the lower-left floor above four large saws. The finish is high on the left, a moon is high on the right, and one A button sits at the far-right end of the lower route.
Finish and moon
Finish: High on the left wall, above the starting side.
Moon: High on the right side of the room. The tested finish worked without collecting it.
Tested route
Run right along the lower route until Oozy depresses the A button. Reverse left immediately and use short repeated jumps as the room slides and the start-side floor rises. Keep returning left until the elevated route carries Oozy into the upper-left finish.
Safer approach and common failures
Safer approach: Do not jump on the outward run. After A triggers, keep left held and jump again only after a landing; lingering beside the button lets the floor move out from under Oozy.
- Jumping unnecessarily on the safe outward run and dropping toward the saws
- Waiting at the A button instead of reversing as the room starts to shift
- Running left without jumping over the newly separated floor sections
- Turning back toward the moon instead of completing the left return
Evidence chain: current-build completion S15; recorded route cross-check S8, approximately 2:56–3:04.
World 4 · Level 2
rotating square crossing
Starting layout
Oozy starts on a left ledge above a row of saws. Three blue square platforms rotate over the gap, the finish is on the far right, and the moon is low near the right side.
Finish and moon
Finish: On the far-right ledge.
Moon: Low on the right side, close to the saw-floor route. The tested finish worked without collecting it.
Tested route
Keep moving right and use short jumps at each landing. Cross the first large rotating square, the smaller middle square and the final large square in order, then continue into the finish on the right.
Safer approach and common failures
Safer approach: Aim near the center of each square and wait for landed contact before jumping again. The tested finish route stays above the saws and does not detour down toward the moon.
- Jumping from the edge of a rotating face and being thrown toward the saws
- Holding a long jump through more than one platform
- Pausing on a steep face until Oozy slides off
- Dropping toward the moon during a finish-only run
Evidence chain: current-build completion S15; recorded route cross-check S8, approximately 3:06–3:14.
World 4 · Level 3
tilting-bar climb
Starting layout
Oozy starts at the bottom center of a tall room. Six thin blue bars tilt through different angles, the finish is high on the right, and the moon is high on the left.
Finish and moon
Finish: High on the right side of the room.
Moon: High on the left side of the room. The tested finish worked without collecting it.
Tested route
From the bottom start, jump right onto the low bar, then steer left to the lower-center bar. Reverse right for the middle-right landing, use the next upward jump to reach the upper bar near the goal, and continue right into the finish.
Safer approach and common failures
Safer approach: Release horizontal input for a moment after each landing so the bar supports Oozy before the next jump. A fall to the bottom is recoverable, but restarting gives a cleaner platform cycle.
- Trying to climb only on the right side and running out of height
- Jumping before a tilted bar supports Oozy
- Overcorrecting in midair and missing the alternating landing
- Falling to the bottom and continuing from an unfavorable bar cycle
Evidence chain: current-build completion S15; recorded route cross-check S8, approximately 3:16–3:22.
World 4 · Level 4
three growth fruits
Starting layout
Oozy starts on the lower-left floor. Three orange growth fruits rise in steps from the far right toward the upper left, with the moon below the upper-left finish.
Finish and moon
Finish: High on the left side of the room.
Moon: On the left below the finish. The tested route collected it; whether it is required was not separately verified.
Tested route
Run along the floor to the far-right, lowest growth fruit. Reverse left and keep using short jumps so the enlarged Oozy touches the middle fruit and then the highest fruit. Continue toward the upper-left finish; the tested route also collected the moon on that approach.
Level 4 boundary: this successful growth route collected the moon near the finish. We have not yet proved a moon-free route, so the requirement stays unknown.
Safer approach and common failures
Safer approach: Make sure the far-right fruit has visibly enlarged Oozy before reversing. On the return, keep moving left so each larger form reaches the next higher fruit instead of falling back to the floor.
- Turning around before touching the lowest fruit
- Running left without jumping high enough for the middle fruit
- Stopping after the second growth before reaching the highest fruit
- Treating the collected moon as proof that every finish requires it
Evidence chain: current-build completion S15; recorded route cross-check S8, approximately 3:26–3:32.
World 4 · Level 5
horizontal-growth gate
Starting layout
Oozy starts on a narrow central pillar above nine saws. Five orange horizontal-growth fruits sit on upper and lower routes, an A button is on the lower-right wall, and the finish is on the lower left behind an A-controlled gate.
Finish and moon
Finish: On the lower-left side, beyond the vertical gate controlled by A.
Moon: Far to the upper left, outside the tested lower finish route. The tested finish worked without collecting it.
Tested route
Jump right through the nearby fruit and the upper-right fruit, then reverse left immediately and keep jumping across the upper route until the far-left fruit stretches Oozy again. Return toward the right, stop jumping and steer left until Oozy drops to the lower-center route. Touch the lower-middle fruit, then move right without jumping; the long body reaches the lower-right fruit and A button across the saw gap. Once the gate drops, hold left along the lower route until Oozy enters the finish.
Level 5 check: use jumps on the upper route, then stop jumping after dropping to the lower-center route. The final run to A works by moving right while the stretched body bridges the saw gap.
Safer approach and common failures
Safer approach: Reverse as soon as the upper-right fruit starts the stretch animation so Oozy does not become pinned against the right wall. After returning from the upper route, wait for a confirmed lower landing before making the no-jump run to A.
- Holding right after the upper-right fruit and becoming pinned beside the wall
- Trying to reach A before collecting enough horizontal-growth fruits
- Continuing to jump on the lower run and climbing back to the upper route
- Turning left before the A button retracts and the gate visibly moves down
Evidence chain: current-build completion S15; recorded route cross-check S8, approximately 3:34–3:58.

Local game-only screenshots include each starting room, the World 4 selector and the World 5 unlock screen. S8 was used only to cross-check route order; no S8 frame is republished. Level 4's moon requirement remains unknown because the completed route collected it.

Rechecked August 2, 2026 against the exact video ID's YouTube storyboards and 638 browser captures sampled every two source seconds. A July 27 note had mistakenly treated frame indices as elapsed seconds and therefore understated the recording as Worlds 1–5; visible labels establish that it reaches World 14. The uploader description calls the moon a target, while the visible tutorial calls that moon optional. Neither statement is generalized to every current Level. No video frame may be republished as site artwork.

Poki's July 2026 release metadata is recorded separately from the developer page and forum launch dates. The moon wording is not treated as proof that every current level has the same completion condition. S13 directly completed the five tested World 1 Levels without collecting their moons.
